EIA/TIA 568 and ISO/IEC 11801 wiring grades: Grade 1 – Unshielded Untwisted wiring. Commonly called inside wire by the Telco community. (Informal designation) Grade 2 – Unshielded twisted pair (UTP) derived from IBM Type 3 spec. (Informal designation) Category 3 – Unshielded twisted pair with 100 ohm impedance and electrical characteristics supporting transmission at frequencies up to 16 MHz. May be used with 10Base-T, 100Base-T4, and 100Base-T2 Ethernet. (Obsolete) Category 4 – Unshielded twisted pair with 100 ohm impedance and electrical characteristics supporting transmission at frequencies up to 20 MHz. May be used with 10Base-T, 100Base-T4, and 100Base-T2 Ethernet. (Obsolete) Category 5 – Unshielded twisted pair with 100 ohm impedance and electrical characteristics supporting transmission at frequencies up to 100 MHz. May be used with 10Base-T, 100Base-T4, 100Base-T2, and 100Base-TX Ethernet. May support 1000Base-T, but cable should be tested. (Superceded by Cat5e) Category 5e – “
